For today's young adults, the experience of being in the age period 18-30 years is, compared with previous generations, quite different. There is more room for exploring and experimenting when lifestyles and life-choices are no longer predetermined, and most things are possible for today's young people. The object of this thesis is to examine young people\2019s experiences in the transition from youth to adulthood and to illuminate those experiences and difficulties that take place during this period. In the study, qualitative interviews were used in four focus groups, divided up in two age categories. The results reveal that the feeling of being an adult arises in the latter part of the period, and that variations between individuals are readily apparent. Creating new and changing old roles, and in particular the adoption of occupational and family roles, are most noticeable during this period. This means that the period in many cases is experienced as confusing and stressful, as responsibility must be taken for the multitude of choices, and change that are made.
